摘　　要：混合电动汽车用MH-Ni电池组是由上百只单体电池进行组合而成的,电池组在频繁的大电流使用过程中,会不断地产生热量;分析了MH-Ni电池在充、放过程中产生热量的3个主要途径,并从提高电池的高温充放电效率、减小欧姆电阻的影响、降低电池的产热速率和产热量,以及如何对电池强制散热、减少电池的热量累积等方面介绍了MH-Ni电池热控制技术的研究现状。Ni-MH power battery for HEV application are stacked by hundred of Ni-MH cells. The bat- teries generated continually heat during charge-discharge at large current. Three main ways to generate heat in Ni-MH batteries during cycles at large current were analyzed. Some methods, such as improving the charge efficiency of Ni-MH cells at high temperature, reducing the ohm resistance of Ni-MH bat- teries , as well as cooling air-flow design for battery-packs, were introduced.
